Frankly if this is not in a manual and the seller is that poor on support, call the maker's support line.
I think it should remember it but if not, call it in.
Is it possible to programme my VIERA E6 Series television to automatically connect to the internet when it is turned on? I mainly use my TV for Netflix and other internet apps, and it is annoying to have to sign in and provide my wifi password every time I turn it on. Does anyone know how make it remember the network?
